For mounting wire rope systems, Fassadengrün uses mounts ('cross clamps') of our own design. Here you can see how these fittings are grouped, as well as indications for the selection of a product appropriate to your wall requirements, including difficult types of walls. All components of the mounts are carefully thought out and coordinated (as you can see below), so any possible damage or mishap in your attachment system can be avoided! >>> Price list
FassadenGrün wire rope systems are grouped in construction styles using the following standard cable mounts:
WM 06093 for Light Kits
WH 08111 for Medium "Eco" Kits
WM 08133 for Medium "Premium" Kits
WH 10151 for Medium "Classic" Kits
WM 12191 for Heavy Kits
WM 12153 for Massive Kits
Our pre-assembled kits with these cable mounts are suitable for almost all wall types with the exception of: external insulation, framework, panelling, and thin-walled concrete elements; for these, special mounts are required. Read on!
Problematic or tricky wall types/surfaces are not a problem; they just require special mounts. Determine your wall type and choose a suitable mount from the tips below. The individual types are named briefly here, but you can find the biggest selection under our Medium Classic Style (Kits). *An extra section is dedicated to insulation and the corresponding mounts.
WM 10081 for thin concrete walls in pre-fab garages, etc.
WM 10083 for timber framework, panelling, panel building materials, etc.
WM 10101 for special cases, also with clamping elements for push-through intallation.
WM 10121 for adhesive (chemical mortar) assembly; also with clamping elements for push-through installaion (link WM 10101).
WM 10151 as a long version of WM 10121, for special cases (link WM 10101)
WH 10181 as a long version of WH 10151, for special cases.
Our Heavy Style (Kit) also offers further special supports:
WM 12161 for massive wood (then without composite mortar, etc.)
WM 12227 for increased wall distance up to 13 cm
WM 12XX2 / WM 12XX4 for many exterior insulation systems (EIFS) up to 6 cm with low/medium loads
WM 12XX8 for many exterior insulation systems (ETICS) up to 12 cm with higher loads and increased wall distance
You can also order the KK 00000 cable clamp heads (nuts) for do-it-yourself cross mounts, for special cable installations (railings, curtains, etc..). These parts, with an open base resemble but are not identical with cross clamps, which have a closed bottom.
For push-through installation, FassadenGrün offers GG 00000 counter-pressure bolt sets, suitable for different thread sizes. These bolts can only be used on metric threaded screws, not on screws with wood threads. The sets are designed to correspond 1:1 to the parts that are already on the shaft of the respective cable mount and screwed against the wall, including gasket, etc.. This means that the sets-- together with the crossheads mentioned above-- are also suitable for do-it-yourself construction of mounts.
The distance of a cable from the wall acts as a lever arm and thus determines the load on the anchor. A high wall clearance creates a high flexural buckling that can bend the mount or even pull it out. FassadenGrün specifies exactly which maximum wall clearances are permitted with which mounts. Many cross mounts are designed in such a way that exceeding the recommended wall distance is not possible.
By tensioning against a wall, the bending point is brought closer to the wall surface (see diagrams 01 and 02), the cantilever length (lever) is shortened, thereby reducing the tension and bending on the mount. Cross mounts M 6-10 come with curved washers with specific (unusual) hole diameters (such as 5.9 mm, 7.8 mm, 9.8 mm), specially manufactured for FassedenGrün. This allows the screw shaft to be securely braced by the support washer.
The load transmitted to the cross mounts by the tensioned cables becomes greater as the distance between the cables and the wall increases. These must be absorbed by the plug system; otherwise, the mounts will be loosened or pulled out during installation. For this reason we use particularly long, reliable rawl plugs and fixings with very high holding values (DM 10030) and even heavy-duty plug-anchors (WM 12153). An optimal attachment is the use of adhesive-gluing when mounting (as used in heavy kits), in which case no anchor/rawl plug is necessary.
The shaft thicknesses of the individual designs are adapted to specific rope diameter. For 1.8 mm, cable cross mounts with a shaft thickness of 6 mm (M6 - light construction) are used. For 3 mm rope, those with 8 or 10 mm (average construction), and for 4 mm rope, those with 12 mm. Problems and damage occur if shafts of wall mounts are not anchored deeply enough into the wall (if the screws themselves are too short, for example), or if they taper out --become thinner-- at the point of maximum stress (at the surface of the wall). None of the screws told by FassadenGrün have this problem.
With their slender shafts, cable mounts from FassadenGrün are not totally rigid, but are designed to be supple, slightly spring-y, allowing them to absorb shock and impact without permanent deformation.
Drill holes of 10 to 16 mm are required for plugging (anchoring) cable cross mounts. In the comparison table you can select your desired cross mount drill-hole diameter. Sufficiently large holes are essential for the previously mentioned high-strength installation. All mounts come equipped with washers (seals). If you are installing in joints, additional washers are available upon request.
All cable cross mounts have a safety slip protection. That means that overloads and strain in the wire rope system are only partially transferred to the mount. In the case of overload, the rope can give, slip out of the clamping head and later be re-tensioned, without incurring damage to the mount or the rawl plugs. Depending on the specific design, grub screws with a conical tip (flat and chamfered) or a ring edge (annular cutting tip) are used to generate the appropriate clamping forces.
